Dispatch Notice

Maximum of 6 hours

Dispatch Trigger

BDRP is an emergency program that reduces Ameren Missouri’s demand during MISO grid emergencies to maintain reliable electricity. Ameren Missouri issues dispatches when the systemwide demand approaches critical peak levels, typically in afternoons with record high temperatures. To ensure a reliable and efficient power grid, your participation is vital

Participation Options

Curtail or transfer electrical load to a back-up generator or qualified storage system.

Enrollment Strategy

Enel will work with you to determine your site’s enrollment value based on the electrical load pattern at your facility, performance in your dispatch readiness test, and information regarding your site’s operations. Enel may adjust this value based upon dispatch performance history and other feedback.

Audit Requirements

Ameren Missouri may audit the portfolio twice per year (summer and winter). This one-hour audit will confirm your ability to deliver your enrolled kW value.

Dispatch Timing & Duration

Dispatches will typically occur between the hours of 6 AM-10 PM. Depending on the season, dispatches are likely to occur in the afternoons between 3 PM – 7 PM in the warmer months and early morning or evening in colder months. Dispatches do not exceed 4 hours. In most cases, Ameren and Enel provide visibility into forecasted events by sending a forecast of dispatch likelihood, followed by an advance notice on the day of an event. Rarely, however, there may be a true grid emergency, and you will have at least one hour to reduce your load.

Baseline Definition

Below are the two baseline options available to customers. Baselines are selected by Enel, with Customer’s input, based on historic interval data, past performance, and anticipated changes in site operations for the upcoming year. Enel will advise Customer which baseline will be used as part of the seasonal enrollment email. 

1. Peak Load Contribution (PLC)

The average peak daily demand taken during the five PLC hours (two hours before, the hour of, and two hours after the MISO seasonal peak hour) across eleven PLC days (five business days before, the day of, and five business days after the seasonal MISO peak)

• Firm Service Level (FSL): The kW level to which a facility should be reduced during a dispatch.
• Customer nomination will be the difference between the PLC and the FSL

2. High 4 of 5

There are two main components:

• Shape: Your baseline shape looks at the highest 4 usage days of the 5 business days prior to the dispatch. Your average demand is calculated in 15-minute intervals.
• Height: If your site's load is running higher than usual, not exceeding 75% of the unadjusted baseline, Ameren will adjust your baseline to reflect real-time consumption. The adjustment window is the two-hour period before the dispatch notification is received.

Performance Measurement

Ameren measures performance for every 15-minute interval during a dispatch by averaging the difference between your site’s demand and the adjusted baseline. Any minimum performance requirements are stated in your agreement.

Keys to Success:

1. Begin your energy reduction as soon as you can before the dispatch start time to ensure you are able to reach your contribution target on time.
2. Execute your full participation plan and verify that equipment does not return to normal operational settings during the dispatch.

Payment Calculation

We calculate payment based on the average delivered kW across all dispatches in the program period, multiplied by the $/kW rate stated in your agreement. If no dispatches occur, your payment is calculated by your average nomination multiplied by the $/kW rate stated in your agreement. 

To achieve your full earning potential, be sure to maintain your energy reduction target throughout every dispatch in a season. Underperformance may result in reduced enrollment and earning potential for future seasons.
